DESCRIPTION:Speakers: Álvaro Díaz Carmona (Universidad de Granada)\nWe p
 resent a basis of dimension-eight Green’s functions involving Standard M
 odel (SM) bosonic fields\, consisting of 86 new operators. Rather than usi
 ng algebraic identities and integration by parts\, we prove the independen
 ce of these interactions in momentum space\, including a discussion on eva
 nescent bosonic operators. Our results pave the way for renormalising the 
 SM effective field theory (SMEFT)\, as well as for performing matching of 
 ultraviolet models onto the SMEFT\, to higher order. To demonstrate the po
 tential of our construction\, we have implemented our basis in matchmakere
 ft and used it to integrate out a heavy singlet scalar and a heavy quadrup
 let scalar up to one loop. We provide the corresponding dimension-eight Wi
 lson coefficients. Likewise\, we show how our results can be easily used t
 o simplify cumbersome redundant Lagrangians arising\, for example\, from i
 ntegrating out heavy fields using the path-integral approach to matching.\
